# Magnitude of acceleration

My prof. made me question what magnitude of acceleration is.. Is it acceleration without direction, i.e -6 m/s/s becomes 6 m/s/s or is it ΔV(speed)/Δt (Sorta like magnitude of acceleration is to acceleration what speed is to velocity)?

The magnitude of acceleration is just how much the object is accelerating regardless of the direction. So if the example is -6 $\frac{m}{s^{2}}$ then you're looking for how much is it accelerating in general which would be 6 $\frac{m}{s^{2}}$ like you said.
